Read and follow these instructions when connecting and using your computer monitor: q q q q q q q q q q q q q q To protect your display from possible damage, do not put excessive pressure on the LCD panel. When moving your monitor, grasp the frame to lift; do not lift the monitor by placing your hand or fingers on the LCD panel. Unplug the monitor if you are not going to use it for an extensive period of time. Unplug the monitor if you need to clean it with a slightly damp cloth. [. . . ] This combination is sometimes called 'glass' or 'cell. ' The LCD cell is assembled into a 'module' by adding the backlight, driver electronics and frame. Q: What is polarization ?A: Polarization is basically directing light to shine in one direction. Electric and magnetic fields oscillate in a direction perpendicular to the propagation of the light beam. The direction of these fields is called the 'polarization direction'. Normal or non-polarized light has fields in several directions; polarized light has a field in only one direction. Q: What differentiates passive matrix LCDs from active matrix LCDs?A: An LCD is made with either a passive matrix or an active matrix display grid. An active matrix has a transistor located at each pixel intersection, requiring less current to control the luminance of a pixel. For this reason, the current in an active matrix display can be switched on and off more frequently, improving the screen refresh time (your mouse pointer will appear to move more smoothly across the screen, for example). The passive matrix LCD has a grid of conductors with pixels located at each intersection in the grid. Q: How does a TFT LCD Panel work?A: On each column and row of the TFT LCD panel, a data source drive and a gate drive are attached, respectively. The molecular arrangement of liquid crystal elements differ according to whether it is impressed with voltage or not. It varies the direction of polarized light and the amount of light by letting it through different arrays of liquid crystal elements. When two polarized filters are arranged vertically on a polarized light pole, the light that passes through the upper polarized panel is turned 90 degrees along with the spiral structure of the liquid crystal molecules and goes through the polarized filter at the bottom. When impressed with voltage, liquid crystal molecules are arranged vertically from the original spiral structure and the direction of the light is not turned through 90 degrees. In this case, light that comes through the top polarized panel may not go through the polarized panel at the bottom. file:///D|/My%20Documents/dfu/X6_model/english/170x6/safety/saf_faq. htm (7 of 9)2005-06-27 1:27:27 PM FAQs (Frequently Asked Questions) Q: What are the advantages of TFT LCD compared with CRT?A: In a CRT monitor, a gun shoots electrons and general light by colliding polarized electrons on fluorescent glass. A TFT LCD monitor is a device that displays an input image by operating a liquid crystal panel. The TFT has a fundamentally different structure than a CRT: Each cell has an active matrix structure and independent active elements. A TFT LCD has two glass panels and the space between them is filled with liquid crystal. When each cell is connected with electrodes and impressed with voltage, the molecular structure of the liquid crystal is altered and controls the amount of inlet lighting to display images. A TFT LCD has several advantages over a CRT, since it can be very thin and no flickering occurs because it does not use the scanning method. Q: Why is vertical frequency of 60Hz optimal for an LCD monitor?For example, an XGA monitor has 1024x3 (R, G, B) x 768 pixels and a higher resolution may not be available without additional software processing.
